ABSTRACT:
A method for applying a silicone rubber material to polyurethane is described wherein a previously processed polyurethane material can be strongly bonded to a silicone rubber material. The silicone rubber material is applied to the polyurethane in a solution and is preferably an acetoxyterminated silicone material, a halogen-terminated silicone material or a combination thereof. The polyurethane and the silicone rubber material are heated at a temperature above about 70.degree. C. to bond the two materials together more strongly than would otherwise occur in the absence of heat.
